what is the slope intercept form of the equation of the line?
Answer:
The slope-intercept form of the equation of the line is:
y = 2/3x + 2
Step-by-step explanation:
The slope-intercept form of the line equation
y = mx+b
where
m is the slopeb is the y-interceptGiven the points
(0, 2)(3, 4)(x₁, y₁) = (0, 2)
(x₂, y₂) = (3, 4)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 0]
= 2 / 3
Thus, the slope of the line = m = 2/3
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept b = 2
now substituting m = 2/3 and b = 2 in the slope-intercept form
y = mx+b
y = 2/3x + 2
Therefore, the slope-intercept form of the equation of the line is:
y = 2/3x + 2

A loan of $7,000 was approved for 36 weeks. Total amount (principal and interest) was paid as S 7388 charged with an 8% annual rate of interest. What is the value of t time in years?
Answer:
.7
Step-by-step explanation:
I'm going to assume that there will just be one final payment at the end. I am also going to discard the fact that the loan was approved for 36 weeks becuase I don't know what to do with that information
I will be using the following formula
[tex]FV=PV(1+i)^n[/tex]
Plugging in the numbers we get
7388=7000(1+.08)^n
We we divide by 7,000 and simplify what we can to get
1.0554=1.08^n
We then write the following log
log(1.0554)/log(1.08)=n
Compute this and get n= .7
A cylinder is 12 feet high and has a diameter of 10 feet. in cubic feet, what is the approximate volume of the cylinder
Answer:
300π or 942.477796077 cubic feet
Step-by-step explanation:
25π*12=300π
The approximate volume of the given cylinder is 942.48 ft³.
What is the volume of the cylinder?The volume of the cylinder is the density which signifies the amount of substance it can hold.
Mathematically,
V = πr²h
where, r is the radius of the cylinder
and h is the height of the cylinder.
It is given that,
Height h of the cylinder = 12 ft
Diameter d of the cylinder = 10 ft
⇒ Radius r = d/2
⇒ r = 10/2
⇒ r = 5 ft
Now, Volume of the cylinder V = πr²h
Putting the values of r and h of given cylinder. We get,
⇒ V = 3.14 × (5 ft)² × 12ft
⇒ V = 3.14 × 25 ft² × 12 ft
⇒ V = 3.14 × 300 ft³
⇒ V ≈ 942.48 ft³
The approximate volume of the given cylinder is 942.48 ft³.

Find the general solution of
dy/dx + 2y =6
Answer:
ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C
Step-by-step explanation:
dy/dx + 2y = 6
This is a first order linear ODE.
p(x) = 2
Integrating factor: I(x) = e^(∫ 2 dx) = e^(2x)
e^(2x)(dy/dx + 2y) = 6e^(2x)
e^(2x) dy + 2ye^(2x) dx = 6e^(2x) dx
Integrate both sides of the equation.
ye^(2x) = 3e^(2x) + C
Thus, the general solution is ye^(2x) - 3e^(2x) = C or (y - 3)e^(2x) = C.

Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 5 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Answer:
2 hours 15 minutes
Step-by-step explanation:
Given that :
Ben's speed = 3 mi/hr
One and half hours after Ben leaves = 1.5 hours
Ben's distance = 3 mi/hr * 1.5 = 4.5 miles
Amanda's speed = 5 mi/hr
Time taken before Amanda catches up:
Let time taken = x
Distance = speed * time
Ben's distance = Amanda's distance
4.5 mi + (3 * x) = 5 * x
4.5 + 3x = 5x
4.5 = 5x - 3x
4.5 = 2x
x = 4.5 / 2
x = 2.25 hours
Time taken = 2.25 * 60 = 135 minutes = 2 hours 15 minutes
It would take Amanda 2.25 hours to catch up with Ben
Speed is the ratio of distance to time. It is given by:
Speed = distance/time
Given that Ben covers a distance d at time t, hence:
3 = d/t
d = 3t
Since Amanda leaves One and a half hours (1.5) after Ben leaves, hence Time = t - 1.5
5 = d/(t - 1.5)
d = 5t - 7.5
Since they catch up, hence:
3t = 5t - 7.5
2t = 7.5
t = 3.75 hours
Time for Amanda = t - 1.5 = 3.75 - 1.5 = 2.25 hours
Hence it would take Amanda 2.25 hours to catch up with Ben.

Answer:
9 [tex]\sqrt{2}[/tex]
Step-by-step explanation:
To find the answer of this equation, you would use the law of sine
so... (18)/sin(90)= (x)/sin(45)
to find for the length of one side simply isolate for x.
Because sin(90) equals 1, you just have to multiply 18 by sin(45) which equals [tex]\sqrt{2}[/tex]/2
